WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 280,676, dated July 3,1883.

Application filed May 11, 1883. (No model.)

To all whom it may concern:

Be it known that I, HIRAM B. Soon, a citizen of the United States ofAmerica, residing at Joliet, in the county of Will and State ofIllinois, have invented certain new and use ful Improvements inWire-Barbing Machines, of which the following is a specification,reference being had therein to the accompanying drawings.

Figure 1 is a side elevation; Fig. 2, a vertical sectional view on line2 of Fig. 1, looking in the direction of the arrow, against the face of.cutting-die 0, showing said die about to descend and shear off the endof the barbstrip D to form a barb; Fig. 3, a similar view, showing thedie 0 as it appears after having descended and cut off a barb Fig. 4, aplan view on the top of the barb-strip, showing the position of the dies0 and c, and the manner in which they shear off the barbs; Fig. 5, aside view of Fig. 2; and Fig. 6, a perspective View of the product ofthe machine, being the barb sheared off from the end of strip D andapplied to the strand-wires.

The nature and object of this machine are to form barbs for wire fencesby cutting them off from the end of a rolled thin strip of metal andattaching them to the strand-wires all at a single operation. Thebarbstrip is shown at .D rolled so as to be about oneinch wide, or.

wide enough to be long enough to make a barb when it is cut off from theend of the strip, and is in shape in cross-section as shown at D inFigs. 2 and 3.

Referring to the drawings, A represents the main frame of the machine,which supports a pair of vertical ways, B B, or traversers, be tweenwhich the sliding head B, containing the upper cutting-off dies,operates vertically in a reciprocating manner by means of a crank andpitman above, as shown in Fig. 1. The sliding head B carries the twodies 0 c and the die 0. The die 0 shears off the barb from the end ofthe barb-strip D, while the two dies 0' 0 cut out notches along thesides of the barb-strip, so as to leave points on each barb, as shown inFig. 4. The view or Fig. 4 is a horizontal section through said dies,and shows their relative positions with each other. The barb-strip Denters the machine horizontally, as shown in Fig. 1, on the bed-plate H,(shown in Fig. 2,) which bed-plate conforms in shape to the barb-strip.This bed-plate H is so set with relation to die 0 that it acts as thelower cutting-off die; or, in other words, the barb is cut off betweenthe forward upper corner of said bed-plate and said die 0 as itdescends. The barb-strip D is fed in the machine by a ratchet-feedbetween a pair of feed-rollers operated by means of the ratchet R, pawl1 crank t, and pitman R, which receives its reciprocating motion from awrist-pin in the slot of the wheel .2 on the crank-shaft that op cratesthe sliding head 13. As said pitman Rreciprocates it rotates thefeed-rollers intermittently and feeds in the barb-strip D as fast asneeded to make a barb at each feed. The bed-plate H has a channel, or,it may be, an aperture, its entire length, directly under the center ofthe barb-strip D, through which to pass the fence-wire 10, which emergesfrom said bed-plate at the locality shown at W in Figs. 2 and 3, betweenthe two lugs 0c of v the barb, directly over the V-shaped depres sion inthe upper surface of the forming-die a. W'hen die 0 descends and shearsoff a barb, it carries it downward onto the upper face of theforming-die a which has its upper face shaped to conform to the shape ofthe barb, except at the center, where it is provided with the V- shapedchannel to receive the two lugs 00 x of the barb. The die 0 presses thebarb down far enough so that the two lugs as x of the barb are drivendown the converging sides of the channel 1) over the strand-wire w untilthe lugs 41; w are closed around under said strandwire, as shown in Fig.3, which firmly coin-- presses and fastens the barb on said strandwire,so that the barb is formed and attached to the strand-wire all at asingle operation. Suitable mechanism, not necessary to be shown indetail, draws the strand wire 10 along the right distance to receiveanother barb in like manner. A second strand wire, w, is also passedinto the machine at the mouth of the twister S, so that when the twisterrotates it twists the two strand-wires w and 10 together,

so as to prevent any rotation of the barb on d it is illustrated andshown in Fig. 1. At the same time when the barb is sheared off the endof the barb-strip the two dies 0 0 (shown more particularly in Fig. 4)out the edges of the barb-strip into notches similar to saw-teeth, asshown in said Fig. 4, and when the die 0 cuts off a barb it cuts it on aline between said teeth, so that the single barb is left pointed at eachend, as shown. The forming-die c is adjustable by means of theset-serews m and m.

Fig. 6 illustrates the product of the machine, it being a section of astrand of finished barbed wire. The bed-plate H lies in the frame a (I,and is covered by the plate a to hold it in posi tion.

The power is applied to the machine by a belt on the band-wheel orpulley F, Fig. 1, on the crankshaft with the flywheel F.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is as follows, to wit:

1. The combination of the frame A, reciprocating sliding head B,cutting-off dies 0 c c, bed-plate H, provided with a channel or aperturefor wire '20, and forming die a having 2 5 the V-shaped groove acrossits upper face, all adapted to operate as and for the purpose set forth.

2. The combination of the cutting-off die a,

bed-plate H, having a longitudinal groove or 0 aperture for wire in, andhaving its upper face conformed in shape to the lower surface ofbarb-strip D, and the forming-die (4", adapted to close the lugs 02 m ofthe barb around the strand wire a, to fasten it thereon, as and for 5being cut off, with a formingdie, (6, adapted 40 to close the lugs ar ofthe barb around and on the strand-wi re 10, as and for the purpose setforth.
